Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1: Please refer to Figures 1-4, The integrated range hood with waste heat utilization in the illustration includes a cooking range 1, and also includes an oil extraction mechanism 2 installed above the cooking range 1 and two water pipes 10 fixedly connected to the top and bottom of one side of the cooking range 1. A combustion chamber 3 is opened on the surface of the cooking range 1, and a fuel chamber 4 is opened on the outer side of the cooking range 1. A stove opening 5 communicating with the fuel chamber 4 is opened in the combustion chamber 3. The cooking range 1 is an L-shaped frame structure. A cavity 6 is provided inside the cooking range 1. An air inlet 7 communicating with the cavity 6 and an air inlet pipe 8 communicating with the air inlet 7 are opened on the side wall of the combustion chamber 3. The outer end of the air inlet pipe 8 is connected to a waste heat utilization mechanism 9, and the waste heat utilization mechanism 9 is installed in the cavity 6. A circulation pump 11 is fixed on the outer side of the cooking range 1, and both the water inlet and the water outlet ends of the circulation pump 11 are communicated with the two water pipes 10 through hoses. The inner ends of the two water pipes 10 are fixed with a transmission pipe 12 extending into the cavity 6.

[0026] It should be noted that: in this solution, the high-temperature gas generated by combustion is poured into the waste heat utilization mechanism 9 through the air inlet 7 and the air inlet pipe 8, and then the water in the cavity 6 is heated to realize the recovery and utilization of the heat in the high-temperature gas. Then, the oil extraction mechanism 2 can adsorb the oil fume generated during cooking.

[0027] It is worth noting that: through the designed combustion chamber 3 and fuel chamber 4, while meeting the supply of combustible gas, the pot is directly placed on the combustion chamber 3, and open fire can also be avoided, making the use safer. At the same time, a water inlet and a water outlet are respectively provided above and below the cooking range 1 for the replenishment and discharge of water in the cavity 6.

[0028] Please refer to Figure 5 and Figure 6 , The waste heat utilization mechanism 9 in the illustration includes a convex tube 13. The small inner diameter end of the convex tube 13 is communicated with the air inlet pipe 8, and the other end is fixedly communicated with an air outlet pipe 14. The air outlet pipe 14 is fixed at the top of the cooking range 1, and a temperature sensor is installed inside the air outlet pipe 14. A double-shaft motor 15 is fixed in the convex tube 13 through a motor bracket. One end of the double-shaft motor 15 is fixedly connected with an adjusting shaft 16 through a coupling, and the other end is fixedly connected with a driving rod 17 through a coupling. The outer end of the adjusting shaft 16 is fixed to the inner wall of the air inlet pipe 8 through a bracket, and a wind guide wheel 18 is fixed at one end of the adjusting shaft 16 close to the double-shaft motor 15. Thread grooves are engraved on the outer side of the other end of the adjusting shaft 16, and a sealing plate 19 is threadedly sleeved on the outer side of the adjusting shaft 16. The diameter of the sealing plate 19 is the same as the inner diameter of the small inner diameter end of the convex tube 13, and a pushing member 20 for abutting against the sealing plate 19 is fixed on the outer side of the adjusting shaft 16. A diffusing member 21 is installed on the outer sides of the air inlet pipe 8 and the convex tube 13;

[0029] It should be noted that: the high-temperature gas is inhaled through the intake pipe 8, then passes through the convex pipe 13, and is discharged through the outlet pipe 14. While the high-temperature gas is flowing, the heat of the high-temperature gas will be absorbed by the water in the cavity 6, thus playing the function of heating the water.

[0030] It is worth noting that: by designing the diffuser 21, the high-temperature gas can flow in the cavity 6 for a longer time, and the effect of heating the water is better. During the flow of the high-temperature gas, the temperature is not sufficient to heat the water. At this time, the biaxial motor 15 rotates to drive the air guide wheel 18 to rotate, so that the gas in the pipe is quickly discharged, so that the gas that cannot play the heating role is discharged, and the high-temperature gas that can play the heating effect floods in.

[0031] Among them, please refer to Figure 5 and Figure 6 , the diffuser 21 shown in the figure includes track plates 22 fixed to the top and bottom of the intake pipe 8. A plurality of diffuser pipes 23 are fixedly communicated with the intake pipe 8 corresponding to the position of the track plates 22. The outer ends of the plurality of diffuser pipes 23 are communicated with a return pipe 24, and the return pipe 24 is communicated with the convex pipe 13. The outer side of the sealing plate 19 is fixed with a shielding plate 25 that fits with the track plates 22 through a connecting plate;

[0032] It should be noted that: through the action of the designed diffuser pipes 23 and the return pipe 24, the high-temperature gas can diffuse in the cavity 6, contact more water, and thus play a heating effect.

[0033] It is worth noting that: after the shielding plate 25 designed covers the diffuser pipes 23 on the track plates 22, the high-temperature gas cannot enter the diffuser pipes 23 and can only be discharged through the convex pipe 13.

[0034] At the same time, please refer to Figure 6 , the pusher 20 shown in the figure is fixed to the limiting plate 26 on the outer side of the adjusting shaft 16. A pushing spring 27 sleeved on the outer side of the adjusting shaft 16 is fixed to the outer side of the limiting plate 26. The outer end of the pushing spring 27 is fixed with a resisting ring 28. The resisting ring 28 is sleeved on the outer side of the adjusting shaft 16, and the resisting ring 28 is located at the outer end of the thread groove;

[0035] It should be noted that: after the sealing plate 19 moves along the adjusting shaft 16 to disengage from the thread groove, in order to enable it to connect to the thread groove again when the adjusting shaft 16 rotates in reverse, through the mutual cooperation of the designed resisting ring 28 and the pushing spring 27, while playing the role of limiting the sealing plate 19, it can also push it to move.

[0036] It should be noted that: after the sealing plate 19 disengages from the threaded groove, although the pushing spring 27 continuously pushes the sealing plate 19, the threaded groove continues to rotate, and the sealing plate 19 cannot be connected to the threaded groove. As a result, the sealing plate 19 always abuts against the abutting ring 28 and cannot be connected to the threaded groove. After the adjusting shaft 16 rotates in reverse, it can be easily connected to the threaded groove.

[0037] In addition, please refer to Figures 1-3 , the oil extraction mechanism 2 in the figure includes an oil extraction pipe 39 fixed on the outer wall of the top end of the cooking range 1. An air inlet 40 is formed on the outer side of the oil extraction pipe 39, and a centrifugal fan 41 is installed at the outer end of the oil extraction pipe 39. The air outlet of the centrifugal fan 41 faces downward and is communicated with an exhaust pipe 42. A ventilation pipe 43 communicating with the tail end of the oil extraction pipe 39 is fixedly communicated on the air outlet pipe 14;

[0038] It should be noted that: by designing the rotation of the centrifugal fan 41, the inside of the oil extraction pipe 39 is made negative pressure, so that the oil fume generated during cooking is inhaled through the air inlet 40, achieving the effect of sucking oil fume.

[0039] Among them, one end of the oil extraction pipe 39 away from the centrifugal fan 41 is inclined upward, and a lamp panel fitting the oil extraction pipe 39 is fixed on the outer wall of the cooking range 1;

[0040] It should be noted that: the design of inclining upward enables the oil fume on the inner wall to be introduced into the exhaust pipe 42 along the oil extraction pipe 39. At the same time, the equipped lamp panel provides illumination during cooking, making cooking more convenient.

[0041] The principle of heat recovery in the combustion gas of the integrated stove: First, during cooking, the user directly places the pot on the combustion chamber 3 on the cooking range 1, and then the combustible gas is supplied through the fuel chamber 4 and ignited. At this time, the bottom of the pot can be heated at a high temperature, and the user starts cooking. At the same time, the high-temperature gas generated by the combustion of the combustible gas will enter the intake pipe 8 through the air inlet 7, and then be discharged through the convex pipe 13 and the air outlet pipe 14 in sequence. During this process, the high-temperature gas contacts the water in the cavity 6, enabling the water to absorb heat. At the same time, a temperature sensor in the air outlet pipe 14 is used to detect the temperature of the gas when it is discharged. If the temperature is higher compared to the temperature to which the water needs to be heated, it indicates that there is still heat in the exhaust gas that has not been adsorbed. By rotating the biaxial motor 15, the adjusting shaft 16 is driven to rotate, so that the sealing plate 19 can move to abut against the intake pipe 8, and at the same time, the baffle plate 25 is driven to move forward to open a plurality of diffusion pipes 23. The high-temperature gas will flow through the diffusion pipes 23 in the cavity 6, increasing the flow distance of the exhaust gas and making the heat absorption effect better;

[0042] When detecting the temperature of the exhaust gas, it is closer to the temperature to which the water needs to be heated. At this time, the heat absorbed by the exhaust gas is very little, and the water cannot be heated efficiently. At this time, by rotating the double-shaft motor 15, the sealing plate 19 is moved to abut against the abutting ring 28, and the baffle plate 25 also abuts against the diffuser pipe 23, so that the gas can only pass through the convex pipe 13, and the guide wheel 18 in the convex pipe 13 rotates, so that the exhaust gas is quickly discharged, and then new high-temperature exhaust gas can rush in, and the heating effect of the water can also be improved.

[0043] Embodiment 2: Please refer to Figures 4-6 , this embodiment further illustrates Embodiment 1. The outer end of the driving rod 17 in the figure is rotatably connected to the air outlet pipe 14 through a bearing and extends into the cavity 6. A driving gear 29 is fixed to the outer end of the driving rod 17, and a toothed belt 30 is sleeved on the outside of the driving gear 29 in a meshing manner. The inner side of the bottom end of the toothed belt 30 is meshed with a driven gear 31, and the inner rod of the driven gear 31 is fixed to the inner wall of the cavity 6 through a bearing seat. Conical gears one 32 are fixed on both sides of the driven gear 31, and a flow-around component 33 meshing with the conical gears one 32 is installed in the cavity 6;

[0044] It should be noted that: by rotating the double-shaft motor 15, the driving rod 17 is driven to rotate, so that the driving gear 29 rotates, and the toothed belt 30 and the driven gear 31 are driven to rotate synchronously. At the same time, the flow-around component 33 will be driven to rotate, so that the water inside the cavity 6 flows.

[0045] Among them, please refer to Figure 4 and Figure 5 , the flow-around component 33 in the figure includes a reciprocating lead screw one 34 and a reciprocating lead screw two 35. The two ends of the reciprocating lead screw one 34 and the reciprocating lead screw two 35 are fixed to the inner wall of the cavity 6 through bearing seats. The reciprocating lead screw one 34 is placed vertically, and the reciprocating lead screw two 35 is placed horizontally. Moving seats 36 are threadedly sleeved on the outside of the reciprocating lead screw one 34 and the reciprocating lead screw two 35. Limiting rods 37 are slidably inserted into the inner sides of the moving seats 36. The limiting rods 37 are fixed to the two bearing seats. The outer sides of the two moving seats 36 are respectively fixed to the outer ends of the two transmission pipes 12, and temperature sensors are fixed on the outer sides of the two moving seats 36. The outer ends of the reciprocating lead screw one 34 and the reciprocating lead screw two 35 are respectively fixed with conical gears two 38 meshing with the two conical gears one 32;

[0046] It should be noted that: through the meshing transmission between the first bevel gear 32 and the second bevel gear 38, the first reciprocating lead screw 34 and the second reciprocating lead screw 35 rotate synchronously, and the moving seat 36 can drive the respective transmission pipes 12 to move. When the temperature sensor detects that the temperature in a certain area is low, the circulation pump 11 can be controlled to start, so that the low-temperature liquid in this area is transported to the other end of the cavity 6, which can cause the water to flow and reduce the temperature difference of the water in the cavity 6.

[0047] Embodiment 3: Please refer to Figure 3 and Figure 7 , this embodiment further illustrates other embodiments. A cover plate 45 is rotatably installed on the surface of the cooking stove 1 in the figure, and a spiral pipe 44 is installed on the outer side of the cover plate 45. Both ends of the spiral pipe 44 fixedly penetrate through the cover plate 45 and extend out from the other side of the cover plate 45. A buckle plate that is buckled with the cover plate 45 is rotatably installed on the outer side of the cooking stove 1;

[0048] It should be noted that: when not cooking, the user can cover the cover plate 45, and then through a hose, both ends of the spiral pipe 44 are respectively communicated with the circulation pump 11 and one of the water delivery pipes 10, so that the spiral pipe 44 is docked with the cavity 6. Under the action of the circulation pump 11, the water in the cavity 6 can enter the spiral pipe 44, and then the user ignites the integrated cooking stove to heat the spiral pipe 44, thereby realizing the active heating of the water in the cavity 6 and facilitating the user's use of hot water.

[0049] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
